autoscale and "equal aspect" mode

I'm using this aspect mode: axes.set_aspect( 'equal',

    > adjustable='datalim' )

    > With several xy line plots on the axes, autoscaling
    > doesn't seem to occur properly. It cuts off part of the
    > data. Is this a known issue? I don't have a simple script
    > to replicate it---I'll have to pull that out of a larger
    > program---but just wanted to check if it is known. I
    > don't see anything in the bug tracker.

matplotlib version number? a lot of work as been done quite recently
on aspect handling. You should test against the latest svn and then
post a complete example describing what is wrong if you are
